After Di Xue ordered everyone to retreat farther away, he used his spiritual power to drive his spatial ring "Ancestral Emperor Ring" to open the spatial crack that he could currently expand to the maximum.

The Ancestral Emperor Ring is a space magic weapon handed down by the Emperor of the Howling Heaven, it is different from other ordinary space magic weapons, it will increase the size of the dimensional space it connects with the improvement of the user's ability, and is mainly affected by the cultivation realm and spiritual power, so the effect is particularly significant in the hands of magicians.

After Emperor Xue's strength has continued to improve recently, and almost all of the four systems of magic are close to the peak realm of the sage, the dimensional space connected by the Ancestral Emperor Ring has expanded to a considerable extent, and all the materials and equipment to be used this time are all brought over from his Ancestral Emperor Ring.

At this time, he drove the Ancestral Emperor Ring, opened a spatial gap in front of him, and poured out all the "black and white" alchemy potions he had brought from Howling Castle before.

I saw a six-pointed star magic array composed of purple light appear in front of him, and black storage boxes kept flying out of thin air from the magic array, and all of these storage boxes were sealed alchemy potions used to build the magnetic ground of the temporary flying saucer take-off and landing field - black and white.

According to Di Xue's plan, they wanted to build at least one temporary flying saucer that could accommodate two "Hercules" military large transport flying saucers at the same time.

The diameter of a "Hercules" is about 110 meters, plus the spare space and some other magic facilities necessary for the take-off and landing field, a "Hercules" needs at least one 150 meters by 150 meters of take-off and landing field, so that the two are 150 meters by 300 meters, a total of 45,000 square meters, and if the area of action of a bottle of alchemy potion is 10 square meters, at least 4,500 bottles of "black and white" alchemy potion are needed.

To be on the safe side, Di Xue brought a total of five thousand bottles of "Black and White", all of which were taken out of the space ring at this time and piled up into a hill on the sand.

Then he took out the array materials and arranged a small illusion magic array on the ground, after the magic array was completed, the light net composed of void light gradually spread from the magic array, until on this vast sandy land, a light net of one hundred and fifty meters by three hundred meters in size was covered on the ground, and every ten square meters in the light net was a small grid.

The next thing is to dig a pit and bury the potion, although it doesn't take much effort to dig a small pit in the sand and bury a bottle of alchemy potion, but there are only eighteen people on Di Xue's side of the four thousand five hundred pits, and it still takes a lot of effort.

After burying the "black and white" alchemy potion, Di Xue said to the Grand Magister Dot: "Mr. Dort, you can start, don't cover too much area with fire magic at first, let's run in the speed first." ”

Grand Magister Dott nodded solemnly, and flew into the sky, and after signaling to Di Xue and the three magicians who came with him, he waved his staff in the sky, and the crimson flames suddenly burned on the sand.

At first, the area covered by the flames was not large, and the Grand Wizard of Dott accurately controlled the magic range within a hundred square meters.

I heard a "hissing" sound from the sand covered in magical flames, and then the sand burned by the flames gradually turned black.

As the flames burned on the sand, within a few minutes, the sand in this 100-square-meter area gradually melted, and the original golden sand and gravel all melted into a black slimy liquid, and released a somewhat unpleasant smell.

After a few more minutes, bubbles began to tumble out on the black liquid formed by the melted sand, all the bubbles were not black, but white, and between the black viscous liquid, a trace of white liquid could be faintly seen, like silver filaments mixed in the black liquid.

At this time, although the sand and gravel melted into a black viscous liquid under the fire magic, it was still composed of earth elements in essence, so they used earth magic to push the viscous black liquid to flow slowly, so that as the temperature became higher and higher, the trace of white liquid that appeared in the black liquid was mixed with the black liquid more evenly.

Gradually, the black and white liquid mixed and turned into a viscous liquid that tended to be silver, and at this time, the Great Wizard of Dott also stopped the fire magic under the instructions of Di Xue, and the magic flame gradually went out.

The magic of the three sage-level earth magicians continued, and after the loss of magic flame burned and heated, the silver viscous liquid was not completely solidified, and the surface was smoothed out with earth magic.

When the surface of the silvery liquid was completely solidified, the whole process took only about half an hour.

At this time, the original sandy land has turned into a dark silver smooth ground, which looks like gold but not gold, like earth but not earth.

It looks good on the surface, Di Xue used the earth element magic to probe the inside of the silver ground, and knew that the internal structure is also very good, and the shaping of this piece of magnetic ground is very successful, it can be called perfect!

He nodded with satisfaction, and said to the Great Wizard Dot and the three sage magicians: "Let's continue like this, let's try to speed up as much as possible in the run-in process, hmm...... In terms of earth magic assistance, it is enough to have two sage-level magicians with the fire magic assistance of the Dot's great magic, so I will also join in, and the two of them rotate in two shifts in the field magic, so please work harder, and stop and rest together when you really need to rest!"

The four magicians didn't have any opinions on Di Xue's arrangement, the fire magic assistance needed to build the magnetic ground was only a bachelor-level magic flame, so it was not a burden at all for a great mage in Dot's house, even if there was no one to replace him and rest, it didn't matter.

So Di Xue also joined the queue of "construction", and under the scorching sun, he and four other magicians began to build a temporary flying saucer landing field in full swing.

......

The most important point of this project is the "black and white" alchemy potion, a bottle of "black and white" potion is actually divided into two parts in the bottle, one part is a black potion, and one part is a white potion.

When the fire magic begins to burn the sand, the special alchemy vial that holds the "black and white" alchemy potion will melt itself when it encounters the magic flame, allowing the two alchemy potions in the bottle to penetrate the ground.

The effect of the black potion is to lower the melting point of the sand, and when mixed with the sand, it does not need to be high temperature to melt the sand, and under the effect of the potion it melts into a special plastic liquid liquid.

The white potion is used to improve the soil quality, it will only begin to spread when the black liquid is boiling, and then gradually merge into the black liquid, adding unique magnetic properties to it, when the silver liquid magnetic soil is mixed to solidify, it forms the magnetic ground of the flying saucer take-off and landing field!

This kind of rapid transformation of the magnetic ground, compared with the polar alchemy metal used in the regular flying saucer take-off and landing places of the empire, is naturally a big difference, barely able to meet the standards for flying saucer take-off and landing, but it will not take too long to be scrapped, but anyway, it is temporary, and the requirements cannot be too high......

In the process of building a temporary flying saucer take-off and landing field, the role of magic is actually only assisting, whether it is fire magic or earth magic, according to the standard, as long as a bachelor's level fire magician and a bachelor's level earth magician can be carried out, and the magic used is also general magic, regardless of faction, as long as it can perform bachelor's level fire magic and earth magic.

There are a group of cultivators specially cultivated by the military in Storm Howling Castle, which are dedicated to similar places that need to use cultivators, while Di Xue only brought three sage-level magicians for speed and efficiency, and the great magic guide hired by the military to be stationed in Wind Howling Castle.

In addition, although there are only five of them in total, because they are all strong cultivators, their speed is faster than that of dozens of bachelor-level magicians working together.

Under the continuous running-in, they built 100 square meters in half an hour at the beginning, and gradually increased to an average of 100 square meters in 10 minutes.

So they hurried and hurried, and in the end, it only took them four days to build 45,000 square meters of basic magnetic floor!

......

It's just that when Di Xue climbed a tall sand dune on the edge of the sand and looked at his work from afar, the corners of his mouth twitched......

Because the construction is carried out in different areas one by one, for example, after the construction of a 100-square-meter piece, the next one will be built next to its edge, so there must be a gap between each piece.

After all, they are not a professional team, and under the gourd painting, the edges of each piece are not so neat...... Most of them are crooked, many of the shapes are not square, trapezoidal, rectangular, and even triangular shapes......

And the color of each piece is also different, although it is all silver, but the deep is dark, and the light is light......

In one word: ugly!

And it's not ordinary ugly! It's very ugly! It's very strange! It's very realm!

Di Xue looked at the 45,000-square-meter temporary flying saucer take-off and landing field, and after being silent for a long time, she said very seriously: "Can I say to the outside world that this is an impressionist style?"

Taylor, who was standing next to him, glanced at him and said with the same seriousness: "Yes, but no one will believe it." ”

Di Xue nodded, and said solemnly: "Yes, it's really not like Impressionism, I should say it's abstraction." ”

Taylor rolled her eyes at him.

Several of the Brotherhood members behind them shivered in the scorching sun from the two of them.

Di Xue waved her hand weakly and said, "Forget it, that's it...... After setting up the spatial information transmission array, notify the Howling Castle to send the engineer troops and logistics troops over, and then there will be nothing for us to do, well, we should be able to start selling tickets tomorrow!"
